What is an exception? - Application Real-Time Monitoring Service

This topic describes how to view the exception analysis details of an application.

Criteria

The exception analysis feature of Application Real-Time Monitoring Service (ARMS) detects Java exceptions. Due to the try...catch statement, exceptions that occur in an interface call may not be detected. If the statement is executed multiple times, an interface call may encounter various exceptions. If an exception affects the response of an interface call without being detected by the try...catch statement, an error is returned.
